How to distinguish "translation" from "displacement"?

Can be distinguished from two shooting methods:

When shaking the lens, the camera position is fixed in place, and the camera can rotate 360 degrees or move up and down with the tripod of auxiliary equipment. People often regard the shaking shots around them as moving and rotating time-lapse photography shots and shots that introduce big scenes.

When the camera is moving, the position of the camera is also moving, and the subject moves with the camera to shoot, so it is necessary to move the tripod or lay a slide rail to shoot. For example, in the 100 meter race, the camera has been following the athletes from beginning to end.
